Project A (Chinese: A計劃; Jyutping: A Gai3 Waak6; fully titled as Jackie Chan's Project A) is a 1983 Hong Kong martial arts action comedy film starring and directed by Jackie Chan, who also wrote the screenplay with Edward Tang, who produced with Leonard Ho and Raymond Chow.

Set in the 19th century in old Hong Kong, Project A blends martial arts with comedy moments and spectacular stunts.

In the late 19th century, Sergeant Dragon Ma is part of the Hong Kong Marine Police's effort to combat pirates, who have been raiding ships for months.

Shortly after this, Captain Chi releases all of the sailors to their commanding officer, and two of the Marine Police's ships get blown up.

Tiring of the blatant corruption in the police force, Dragon arrests Chiang out and tells Tin-tsu to take the credit.

After pushing everyone into the water and making off with the guns, Fei hides the rifles inside a log and marks it with a red flag.

After teaming up with Fei, being tortured for information about the rifles, and falling from the face of a clock tower, Dragon is tracked down by the police for a for a third time, and they help him get away as they arrest the gangsters.

Having overheard the conversation, Dragon confronts the Colonel and convinces him that the gangsters and the pirates will never fear the law if the police force are corrupt.

It is agreed that Dragon will assume all responsibility for the mission to save the hostages, and the Colonel allows the Marine Police to be brought back into full force.

After a lot of tricky undercover work, the cavalry arrives, and there is a final confrontation in the middle of the pirate's lair.

Dragon, Tin-tsu, and Fei engage in a hand-to-hand battle with San Pao, eventually killing him with a hand grenade when he's rolled into the carpet.

Edward Tang and the production team felt that a period film could still have success if it had sufficient action, and so researched the history of Hong Kong during the time of pirates for Project A.

Jackie and the Golden Harvest team employ some researchers to come up with background for this story about pirates in Hong Kong and are not really concerned at all about depicting the film in the exact era.

In rehearsal for the clock tower fall, Chan took a week to build the courage to drop from such a great height.

Due to the nature of his films, Chan's outtakes are a combination of comedic moments and injuries sustained whilst he and his team perform stunts and fight sequences.

According to Chan, Project A was an evolution of the action stunt work he had already been doing in earlier kung fu comedy films since The Young Master (1980).

Reportedly, in Japan, Emperor Showa's fondness of the film and eagerness to see a sequel led Chan to make Project A Part II.
